Abstract:
A mounting bracket for mounting an equipment housing such as a telecommunications equipment shelf to a rack, the mounting bracket comprising a bracket body for rigid attachment to the housing, a fastener for rigid attachment to the rack, and a damping member coupling the fastener to the bracket body. The damping member isolates the equipment within the housing from the rack such that earthquake vibration resistance is improved. The damping member is preferably an elastomeric material such as very high density silicone. It is preferably configured to preferentially absorb vibrations at resonant frequencies of the rack structure.

A jack and chassis assembly includes a baluns interface connected directly to the in/out wire wrap pins on the jacks. This helps to convert 75 ohm coaxial signals to 120 ohm twisted pair interface signals for equipment connections. The jack and chassis assembly includes at least one jack, a chassis defining a first frame holding the jack, a circuit board mounted to the first frame and in electrical contact with the jack, and a balun in electrical contact with the jack. Methods for assembling a jack and chassis assembly include mounting a jack onto a frame, providing a second frame holding a balun, and connecting the jack to the balun. A chassis assembly includes a first frame, and a second frame, with the first frame being mounted within the second frame. A method for servicing a jack assembly includes providing jacks mounted in a first frame in a chassis, providing a circuit board secured to the first frame and in electrical connection with each of the jacks, removing the first frame holding the jacks from a second frame supporting a panel of baluns electrically connected to the jacks, and providing a space between the plurality of jacks and the panel of baluns sufficient to permit service access to the jacks.
Abstract:
The present invention is directed to a shelf for housing PCPs. A backplane extends across the shelf. A connector module having the OAM&P connectors is electrically connected to the backplane and has two positions. In one position it extends sideways from the shelf with the connectors in a front to rear direction. In the second position, the OAM&P connector module is substantially flush with the side of the shelf.

A telecommunications device including a plurality of splitter cards mounted in a chassis. The device also includes a circuit board and plurality of card edge connectors for providing electrical connections between the splitter cards and the circuit board. The device further includes POTS connectors, LINE connectors and DATA connectors. The circuit board includes a first layer having first tracings that electrically connect contacts of at least one of the POTS, LINE or DATA connectors to at least one of the card edge connectors; a second layer having second tracings that electrically connect contacts of at least one of the POTS, LINE or DATA connectors to at least one of the card edge connectors; and a third layer having third tracings that electrically connect contacts of at least one of the POTS, LINE or DATA connectors to at least one of the card edge connectors. The second layer is positioned between the first and third layers. A majority of the second layer is covered by a grounding plane. The grounding plane and the second tracings are co-planar such that the grounding plane adds no additional thickness to the second layer. The grounding plane is positioned between the first and third tracings to reduce cross-talk between the first and third tracings.
